introduction methylene blue was first described for the treatment of methemoglobinemia but practical usage of the compound for surgical purpose is common. the aim of this report is to describe a case of hemolysis in neonatal period as a potential hazard of methylene blue toxicity without presence of g6pd deficiency. case presentation in october 2015, a 36-week ga female infant with 2.05 kg weig...

We present initial results from a wide-field, multicolour imaging project, designed to study galaxy evolution in X-ray-selected clusters at intermediate ðz , 0:25Þ and high redshifts ðz , 0:5Þ. We give blue galaxy fractions from eight X-ray-selected clusters, drawn from a combined sample of three X-ray surveys. We find that all the clusters exhibit excess blue galaxy populations over the number...

CLINICAL PRESENTATION A 16 year old girl was referred to dermatology clinic with bilateral blue gray hyperpigmented patches on her cheeks since birth. Upon close physical examination, scleral blue-gray hyperpigmentation was observed in both her eyes (Figure 1). She also had a blanchable red patch with poorly defined borders on her right cheek (Figure 2). Ophthalmology consultation further revea...

PURPOSE To determine whether blue light induces photoreversal of rhodopsin bleaching in vivo. METHODS Eyes of anesthetized albino rats were exposed to either green (550 nm) or deep blue (403 nm) light, and the time course of rhodopsin bleaching was determined. Rhodopsin was isolated from whole retinas by detergent extraction and measured photometrically. To inhibit photoreversal of bleaching,...

Mixtures of methylene blue and azure-2 are stated to stain neutral lipid droplets an intense dark blue in 0-5-10 ,um-thick Araldite sections of osmiumfixed kidney (Muehrcke, Mandal, Volini, and Epstein, 1969; Tobian, Ishii, and Duke, 1969). Neither group of investigators, however, detail either the composition of the stain or the method. A modification of the methylene blue-azure-2 method of Ri...

A 53-year-old-man with prostate cancer underwent prostate brachytherapy one month ago. Since then, he has experienced increased urinary frequency, dysuria, perineal discomfort, reduced urinary stream velocity, and nocturia. The patient was prescribed the following medications to relieve his urinary frequency and dysuria: sulfamethoxazole/trimethoprim, ciprofloxacin, tamsulosin, methylprednisolo...
